KEY POINTSThe prime minister is under intense pressure to step down after U-turning on her “mini-budget.”However, she told the House of Commons she was a “not a quitter” as she was questioned by politicians.Any resignation leaves open the question of who would succeed her and what direction they would take the fractured party in.LONDON — British Prime Minister Liz Truss insisted Wednesday she was a “fighter not a quitter” as she was grilled by parliamentarians for the first time since being forced to scrap almost all of her flagship fiscal policies.Truss said she had “acted in the national interest to make sure that we have economic stability,” while also starting the session by saying she was “sorry” and had “made mistakes.”The row-back of her huge program of tax cuts, originally announced on Sept. 23, came after it sparked massive volatility in financial markets, with the pound plunging against the dollar and U.K. government bonds being sold off at such a rapid rate it threatened to topple pension funds. Mortgage deals were also pulled as interest rate hike expectations rose rapidly.Full details of the government’s new economic policies are expected Oct. 31, along with an independent economic forecast.Attack lines from opposition leader Keir Starmer during Prime Minister’s Questions on Wednesday included questions over how the public could trust a leader whose “promises didn’t last a week”; branding her policies “fantasy economics”; and accusing Truss of crashing the economy.“I had to take the decision because of the economic situation to adjust our policies,” Truss said. She added that interest rates were rising globally and economic forecasts had worsened.CNBC.com
